Nasopharyngeal swab polymerase chain reaction (RT-PCR) can diagnose only current or recent infection; testing for antibody responses against SARS-CoV-2 could enhance the ability to expedite reinstatement of services, while ensuring patient and staff safety. Tests are now available for immunoglobulin (Ig) G against the SARS-CoV-2 nucleocapsid protein; the Abbott SARS-CoV-2 IgG ELISA is reported to have high specificity We previously reported that 32% of HCW testing positive for SARS-CoV-2 on nasopharyngeal swab were asymptomatic at the time. 2 Symptomatic and asymptomatic SARS-CoV-2 positive adults have similar viral loads and infectious virus isolation. Of those testing positive for SARS-CoV-2 IgG, 39% had an earlier negative nasopharyngeal swab. 5 Both symptomatic and asymptomatic infections were associated with SARS-COV-2 IgG antibodies, as were 10% of	./cache/cord-322204-kc7dy2za.txt	./txt/cord-322204-kc7dy2za.txt
